Introduction

This chapter lists what you need to get started, provides an overview of the
PXI hardware and the NI-CAN software for Windows NT, and describes
optional equipment you can order.

What You Need to Get Started

Make sure you have all of the following items before you attempt to install
the hardware and software:

❑ Windows NT 3.51 or later installed on your computer

– PXI-8461 one port
– PXI-8461 two port
– PXI-8460 one port
– PXI-8460 two port

❑ 3.5 in., high-density (1.44 MB) disks, which are included in your kit:

– NI-CAN Software for Windows 95/98/NT

Version 1.3
(Disk x of 3)

1

❑ CAN interface cables that meet the requirements in Appendix B,

Cabling Requirements for PXI-8461 High-Speed CAN or Appendix C,
Cabling Requirements for PXI-8460 Low-Speed CAN.

Hardware Overview

The PXI-8461 and PXI-8460 (one port and two port) are software
configurable and compliant with the PXI Specification and CompactPCI
Specification. With a PXI-8461 or PXI-8460 board, you can make your
PXI or CompactPCI chassis communicate with and control CAN devices.

The PXI-8461 physical layer fully conforms to the ISO 11898
physical layer specification for CAN and is optically isolated to 500 V.
The PXI-8460 physical layer conforms to the ISO 11519-2 physical layer

© National Instruments Corporation 1-1 PXI-8461 or PXI-8460 and NI-CAN for Windows NT

Chapter 1 Introduction

specification for CAN and is also optically isolated to 500 V. CAN
interfacing is accomplished using the Intel 82527 CAN controller chip.
The PXI-8461 supports a wide variety of transfer rates up to 1 Mb/s.
The PXI-8460 supports rates up to 125 kb/s. The CAN physical layer on the
PXI-8461 and PXI-8460 can be powered either internally (from the board)
or externally (from the bus cable power). The power source for the CAN
physical layer for each port is configured with a jumper.

PXI-8461 boards are available with two physical connector types:

• DB-9 D-Sub

• Combicon-style pluggable screw terminals
PXI-8460 boards are available with DB-9 D-Sub connectors.
The PXI-8461 and PXI-8460 use the Intel 386EX embedded processor

to implement time-critical features provided by the NI-CAN software.
The PXI-8461 and PXI-8460 communicate with the NI-CAN driver
through on-board shared memory and an interrupt.

NI-CAN Software Overview

The NI-CAN software includes a native, 32-bit multitasking Windows NT
kernel driver. The NI-CAN software is fully integrated into the
Windows NT operating system. You can configure it through the
Windo ws NT Control Panel and uninstall it through the Add/Remove
Programs applet of the Control Panel.

The NI-CAN software for Windows NT supports the concurrent use of
multiple CAN boards. For example, you can use both a PXI-8461 and
PCMCIA-CAN in the same system at the same time.

The NI-CAN software, along with the PXI hardware, transforms your
computer into a CAN interface with complete communications and bus
management capability. The NI-CAN software includes the following
components:

• Firmware (runs on embedded Intel 386EX)

• Device driver

• Diagnostic test utility

• Configuration utility

PXI-8461 or PXI-8460 and NI-CAN for Windows NT 1-2 www.natinst.com

• Language interface libraries for Microsoft Visual C/C++ 2.0 or later,
LabWindows/CVI 4.0 or later, and LabVIEW 4.0 or later

• Example programs that use NI-CAN functions

Optional Programming Tools

Your kit includes the NI-CAN software for Windows NT. In addition,
you can order the LabWindows/CVI, LabVIEW, or BridgeVIEW software
from National Instruments.

LabWindows/CVI is an interactive ANSI C development environment for
building test and measurement and instrument control systems. It includes
interactive code-generation tools and a graphical editor for b uilding custom
user interfaces. It also includes built-in libraries for IEEE 488.2, VXI,
RS-232 control, and plug-in data acquisition. When you order
LabWindows/CVI, you also get hundreds of complete instrument drivers,
which are modular, source-code programs that handle the communication
with your instrument so that you do not have to learn the programming
details.

LabVIEW is a complete programming environment that departs from the
sequential nature of traditional programming languages and features a
graphical programming environment. It includes all the tools needed for
instrument control, data acquisition, analysis, and presentation. LabVIEW
also includes an extensive instrument driver library.

Chapter 1 Introduction

BridgeVIEW is a radical departure from traditional automation software
that provides a flexible program development system for a variety of
DeviceNet applications including general manufacturing, test, and control.
Leveraging National Instruments patented graphical programming
language G (otherwise known as LabVIEW), BridgeVIEW gives you the
ability to integrate functionality in a way that is not possible with traditional
automation software. In addition to the programming advantages of G,
BridgeVIEW also provides a number of powerful features for the
development of your industrial automation application: graphical HMI
(Human Machine Interface); ease of use; fill-in-the-blank configuration
utilities; HMI G Wizard for simplified HMI development; historical data
collection and trending; alarm and event reporting and logging; security;
and connectivity to PLCs and industrial device networks like DeviceNet.

BridgeVIEW, contact National Instruments.
